Description

Technical Field

[0001] This utility model relates to the field of mechanical structure technology, and in particular to a thin-walled wire guard structure for preventing pre-installed screws from falling off. Background Technology

[0002] Airborne products are trending towards a more standardized and modular design, dividing them into multiple independent components with interchangeable interfaces. This allows for the fulfillment of diverse mission requirements through component replacement. To reduce the storage and management requirements of standard parts, these components need to be securely attached to each component and designed to prevent them from falling off.

[0003] Cable guards are components used on airborne products to protect external cables. They are typically connected and fixed to the airborne product using screws and tightened with straps. Existing anti-detachment designs mainly fall into two categories: the first involves directly tapping threads into the mounting component, making the screw unable to detach after being screwed in. This method requires a certain number of threads on the screw and is unsuitable for thin-walled parts. The second method involves inserting a hollow rivet between the screw and the mounting component; the screw cannot detach itself after the rivet deforms. This method lacks adjustment space for the screw, making assembly difficult and inconvenient to use. Neither of the existing anti-detachment designs meets the requirements of airborne products for low maintenance reliability and high assembly efficiency for cable guard assemblies. Therefore, a new screw anti-detachment structure for thin-walled cable guards must be designed. Utility Model Content

[0004] The purpose of this utility model is to disclose a structure for preventing the pre-installed screws from falling off thin-walled wire guards, so as to improve the assembly efficiency of thin-walled wire guards.

[0005] To achieve the above objectives, the pre-installed screw thin-walled wire guard anti-detachment structure disclosed in this utility model includes: The mounting groove includes holes A and B distributed at both ends, and a connecting section between holes A and B, wherein the width of the connecting section is equal to the diameter of hole A. The screw has a recessed portion between its head and the threaded section, with a diameter less than or equal to that of hole A. The recessed portion is displaceable within the connecting section. The major diameter of the threaded section is greater than the width of the connecting section and less than the diameter of hole B. The rivet is used to fill the B hole by riveting deformation after the recess of the screw is embedded in the A hole of the mounting groove or the connecting segment.

[0006] Preferably, the mounting grooves are symmetrically distributed along the central axis of the thin-walled wire guard plate. Similarly, the mounting grooves can also be axisymmetric structures. Further, the axis of symmetry of the mounting grooves is parallel to the central axis of the thin-walled wire guard plate.

[0007] Preferably, the tip of the screw before the threaded section has a frustum structure, which facilitates quick alignment with the threaded hole during use. Similarly, the transition section between the threaded section and the recessed portion of the screw can also have a frustum structure. On the one hand, this facilitates processing together with the aforementioned pointed frustum; on the other hand, it also allows for more flexible viewing space for the user during use, thereby saving the user's time.

[0008] Preferably, the length of the connecting segment is greater than the sum of the radius of hole B and three times the radius of hole A, thereby facilitating the user to pre-install two or more screws in certain special scenarios or to reserve more adjustment space for a single screw.

[0009] This utility model has the following beneficial effects: With its simple structure, low processing cost, and applicability to thin-walled parts, this design ensures that the screws have a certain adjustment range while achieving the anti-loosening function, facilitating the installation of the screws with other components and enhancing the protection capability and assembly efficiency of the cable guard assembly.

[0015] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0016] Example 1 This embodiment discloses a thin-walled wire guard plate structure for preventing pre-installed screws from falling off, referring to... Figure 1 and Figure 2 ,include: The mounting groove formed on the thin-walled wire protection plate 1 includes holes A and B distributed at both ends, and a connecting section between holes A and B, the width of which is equal to the diameter of hole A.

[0017] Screw 2 has a recessed portion between the head and the threaded section, with a hole diameter less than or equal to that of hole A. The recessed portion can be displaced within the connecting section. The major diameter of the threaded section is greater than the width of the connecting section and less than the diameter of hole B.

[0018] Rivet 3 is used to fill hole B by riveting deformation after the recess of screw 2 is embedded in hole A of the mounting groove or the connecting section.

[0019] Reference Figure 3 The assembly process based on the above structure of this utility model includes the following steps: S1: A mounting slot is cut into the cable protector. The mounting slot has a large end (i.e., end B) and a small end (i.e., end A). The large end is where the screw is inserted into the cable protector, and the small end is the final installation position of the screw on the cable protector.

[0020] S2: Pass the screw through the wire guard plate at the large end, and place the screw close to the mounting groove at the narrow end.

[0021] S3: Move the screw to the small end of the mounting slot, which is the final installation position.

[0022] S4: Fix the rivet at the large end of the mounting slot to limit the screw and complete the anti-loosening function.

[0023] In this embodiment, the mounting grooves are symmetrically distributed along the central axis of the thin-walled wire guard plate 1. Similarly, the mounting grooves can also be axisymmetric structures. Furthermore, the axis of symmetry of the mounting grooves is parallel to the central axis of the thin-walled wire guard plate 1.

[0024] In this embodiment, the tip of the screw 2 before the threaded section is a frustum structure, which facilitates quick alignment with the threaded hole during use. Similarly, the transition section between the threaded section and the recessed part of the screw 2 can also be a frustum structure. On the one hand, this facilitates processing together with the aforementioned pointed frustum; on the other hand, it also allows for more flexible viewing space for the user during use, thereby saving the user's time.

[0025] Preferably, in this embodiment, the length of the connecting segment is greater than the sum of the radius of hole B and three times the radius of hole A, thereby facilitating the user to pre-install two or more screws 2 in certain special scenarios or to reserve more adjustment space for a single screw 2.

[0026] In summary, this utility model has the following beneficial effects: With its simple structure, low processing cost, and applicability to thin-walled parts, it ensures that screw 2 has a certain adjustment space while achieving the anti-loosening function, which facilitates the installation of screw 2 with other components and enhances the protection capability and assembly efficiency of the wire guard assembly.
